...most of it is just "trickery" to get you to buy THEIR products. I do believe that there are some "modern" or latter day stuff that is good but is it really better than what worked years ago. Maybe some, maybe not on others. If it works for you then use it. A problem is what worked years ago has been taken off the shelf and replaced with "repackaged goods".
Had the same problem today that I'm talking about. Went to THREE stores before I found the Sanding Sealer I was looking for and been using for over 30 years. Lowes was a joke!
